GEARING.

rossore.

inga part of this specification.

My invention relates to meat cutters, coffee mills, grinding machines and the like, and. the primary object of the invention is to so design the construction that the machine may be driven directly by a small internal combustion engine with the casing and driving shaft of the engine directly connected With the driving shaft and casing of the machine to be driven, so that the two machines may form a single machine which can be moved from place to place as desired, and in Whichtlie casing of the driving` engine is so constructed and arranged, that the driven machine may be readily and easily disconnected for cleaning or otherwise, and other machines for analogous purposes may be at will substituted therefor.

My invention consists in its essentials of a suitable base, upon which the driving motor is supported With the machine to be driven thereby also' supported on the base either directly, or as a part of the motor casing, with.'

direct gearing connection between the driving shafts of the two machines and the necessary friction clutch intermediate the driving and the driven machine, whereby the operation of the driven machine may be stopped without stopping the driving engine and whereby th e enginemay be started Without the load. W'it-h this construction, the entire. driving power is self contained in the apparatus, and no connection of any kind is required with any extraneous source of porter. The various constructions of lgrinding and chopping machines may in this way be mechanically operated by power ivlierever desired Without reference to any fixed power supply, and the self contained ma chine as a whole may be moved from place to place as the necessities of the location or n i 2G is provided with a tongue 27 which enf f gages Within a slot in the outer end of a other requirement may demand.

of-'the driving mechanism taken on the lines 2, 2, of Fig. The supporting metal base for the appie ratus is indicated by 1, and this base is divided into suitable compartments for holding the fuel and other necessary liquids for operating the engine. As illustrated for the preferred construction, 2 indicates the chamber for the liquid fuel; '3 the chamber for the lubricating oil, and 4 the chamber for the Water jacket for the engine cylinder.

The driving engine may be of any convenient construction of internal combustion engine, but I prefer the small vertical typ'e tivo-cycle engine, in Which 5 indicates the crank case; 6V the engine cylinder with Water jacket compartment 7 8 is the piston with piston rod 9 coupled to the crank shaft l0, which is mounted in suitable bearings in the crank case, and is provided at one end with the fly wheel 11. At the opposite end, the crank shaft 10 projects into thegear casing 12, and in this casing the pinion 13 is keyed to the crank shaft. The governor for the engine is indicated at 111, While 15 indicates the timer with handle 16 for controlling the ignition. The governor is mounted on the vertical shaft 17 upon Which is secured a spiral indicated at 18, which is driven by a similar gear mounted on the crank shaft 10, so that thel governor shaft is driven in proper timed relation with the engine shaft. 0n the lower end of this shaft connection is made with three pumps 19, 20 and 21, for feeding and circulating the Water for the Water acket, lubricating oil and the fuel. The details of the construction of these variv'ous parts of the engine are not illustrated struction, provided ivith aforcing conveyor.

25, which is formed with the shaft 26, having its bearing in thc hub 23 of the meat cutter casing. The outer end of this shaft sleeve 28 upon which is loosely mounted the gear 29 which meshes with the pinion 13 on for driving other machines for analogous ried by the grooved collari which is snp- 'ter is held in position in the socket on the gear casing ofthe maohineby the thumbthe crank shaft. Keyed on this5 sleeve- 28 is a collar 30, and mounted on this cbliar 30, inside of the flange orrim of the gear 29, is a split ring 3l. This split ring is expanded by a beveled pin-32, which projects with its` beveled edge between the open portions o the ring, and is actuated by the pin 33 carsCreW 37.

It will be evidentfrom the foregoing de scription that the meat cutter can be removed at a moments notice for cleaning, or for placing in a refrigerator, to avoid cleaning after each operation, by releasing the thumb screw 3 7..

For' the purpose lof utilizing the engine purposes such as coee mills, grinders and.

the like, the machine will be formed with a hub portion to .tit withinl the socket iii the l gear casing and with a driving shaft prol vided with a tongue to couple same to the l sleeve 28 on the gear casing.'

' I ain aW/are that it is old to provide an i electric motor with a gear casing for attach l ing meat cutters and analogous machines E thereto, so' that Such machines may be directly driven by the motor. With such machine, however, the operation of the motor is dependent on the electric supply, and i knowoif no case where machines for grind ing, meat cutting and the like have been driven by a seit' contained internal minibus tion engine, so that the apparatus can be vmoved from place' to place, and used witl- 'out regard to any fixed source of supply for the power.

`*Hauling thus described' my invention, what I claim as new and desire to secure by liet ters Patent, is:-A

1. ln combination with a driving shaft, :i support therefor, a shaft to be driven thereby, a support for the driven shaft, a clutch member, driving connection between the clutch member and the driving shaft, means to detachably connect said clutch to the driven shaft, and means to detaeliably se eure the support for the driven shaft to the support for the driving shaft.

2. In combination with a driving shaft, a i

support therefor, a shaft to be driven thereby, a support for the driven shaft, a clutch member, driving connection between the clutch member and the driving shaft, a supn port for the clutch member mounted on the driving shaft support, means for detachably connecting said clutch. member to the driven shaft, and means `Jfior detachably securing the support ortbe driven shaft to the driv ing shaft support.

3. vIn combination with a driving sl'ia't, a

support therefor, a :hatt to be driien there Y by, a support for the driven shaft, a, clutch member, means in the support ,tor the driving shaft for mounting the clutch member, a sleeve at one end thereof to receive. a sleeve on the support for the shaft te be driven, de

,.tachable means 'for securing said sleeves to gether, and detachable connection between the driven shaft and the clutch member.
